Mist humidifiers are designed to raise the humidity levels in a home and to purify the air at the same time. This helps to reduce problems that can occur from dry air, problems that include an increased risk of sinus infections or an increased likelihood of catching the flu. And that is what makes them such a great addition to any home.

The best warm mist humidifiers also convey a few additional benefits over their cool mist cousins. Bacteria are less likely to breed in warm mist humidifiers, and they’re also great for winter use to prevent colds and nasal infections. That’s why we’ve decided to list the ten best models below.

A Guide To Buying A Quality Humidifier

In the good old days when consumers needed a humidifier, they had it pretty easy. There wasn’t a large variety of different models available, so the consumer could just head down to their local drugstore and pick up whatever model they had. Usually, that was good enough for most people and people didn’t feel like they had to put up with a model that wasn’t right for them.

Nowadays, things are a little bit different. Now consumers are used to the wide variety of different humidifiers, so if they don’t find one that fits in perfectly with their needs, then they feel like they’ve been slighted in some way. And this leads many people to spend hours scrolling through countless humidifier models to find the one they’re not going to be disappointed in using. 

We want to take some of the pain out of buying these products, so we’ve decided to write a guide on the subject. It’s our hope that this guide will help all of our readers find the humidifier that suits their needs, so they don’t have to search through a variety of different models. Does that sound okay? Well, if it does, then let’s begin our buying guide by choosing between the best warm mist humidifiers and cool mist humidifiers. 

Warm Mist Humidifiers

Warm mist humidifiers are one of the cheapest humidifier options and are good for raising the humidity levels in the home when the air is too dry. This makes this a good product for using during the winter months to keep your sinuses in good condition. Dry sinuses can make a person more susceptible to developing respiratory infections, so these humidifiers can be good as a preventive measure during the cold winter months.

Unfortunately, once a person has developed a respiratory infection such as a cold or maybe a sinus infection, then they’re going to want to avoid using a warm mist humidifier. That’s because these warm mist humidifiers can cause mucous membranes to swell slightly and this can make it more difficult for sick people to breathe. Just something people should think about when purchasing a new warm mist humidifier. 

Cool Mist Humidifiers

Many of the humidifier models sold nowadays are the cool mist variety, so they should be easy to find. These are the humidifiers that consumers might want to purchase if they’re dealing with some sort of cold or respiratory infection. They do tend to costs a little bit more than cool mist humidifiers but when a person is dealing with a cold, the price difference can be a minor inconvenience compared to the relief they’ll feel from using it. 

Think About The Size Of The Model Needed

The next thing that the consumer is going to want to think about when choosing a new humidifier is the size of the room or rooms they need it to service. If the consumer just wants to use the model while they’re sleeping, then a tabletop model might be appropriate for their needs. On the other hand, if they’re trying to use the humidifier for several rooms or the entire home, then they’re going to have to choose a larger model. 

Think About How Many Levels Of Mist It Provides

Does the humidifier provide just one steady stream of mist or is there a way for the consumer to set the mist as they desire? That’s the next question the consumer should ask themselves. Some models just put out a steady stream, but other models allow the consumer to set the appropriate mist level. 

For example, one of the humidifiers we’ve reviewed has three different mist levels. On low, the unit produces 200 mL an hour, on medium the unit produces 300 mL of mist an hour, and on high the unit produces 550 mL an hour.  

Think About Adjustable Nozzles

Another feature that can make or break an otherwise ordinarily fine humidifier is adjustable nozzles. While some of the cheaper models only point the mist in one direction—usually straight up, some of the higher quality models have nozzles that can be adjusted. Some of these models allow for a 180-degree rotation, while others allow for a full 360-degrees of rotation. Rotating nozzles can be a great way of putting mist exactly where it’s needed. 

Let’s Talk About The Humidistat

Another thing that the consumer might want to consider is purchasing a model with a humidistat. A humidistat will shut the unit off when it has reached a particular humidity level. This can save the consumer some money or prevent the unit from running out of water prematurely. Not all humidifiers have this feature, however, so consumers should think about whether they need it or not. 

Remote Control Operation

Some of the models that we’ve liked had remote control operation and we think that it can be a very handy feature for a unit to have. A feature that allows the consumer to turn on or off the unit without getting up from their recliner or out of bed. 

Some Final Features To Consider

As we come to the conclusion of the guide, we thought that we’d list some of the other features that consumers might want to consider before they purchase a new warm mist humidifier. Although not all of the features below will be wanted by everyone, there are some features that consumers might want to think about before they put down good money on a new humidifier.

  • Child Safety Locks
  • Aromatherapy Boxes
  • Built-In Timer
